Novak Djokovic and Milos Raonic were Friday's opening singles winners, as Serbia and visiting Canada are tied at 1-1 in their best-of-five Davis Cup semifinal.
In the opening rubber, the hosts' world No. 1 star Djokovic rolled past Vasek Pospisil 6-2, 6-0, 6-4 in 1 hour, 40 minutes, as the Serbian stalwart piled up six service breaks, while Pospisil did not enjoy even one break-point chance in the predictable setback.
The 41st-ranked 23-year-old Pospisil popped nine aces in a losing effort indoors on the red clay at Belgrade Arena.
The Australian Open champion Djokovic is fresh off his runner-up finish at the U.S. Open on Monday. He was also the runner-up at Wimbledon in July. The super Serb, who is now 23-7 lifetime in his Davis Cup singles outings, led his country to its' lone Davis Cup title three years ago.
In Friday's dramatic nightcap in Belgrade, the world No. 11 Raonic got the Canadians on the board with a grueling 5-7, 6-3, 3-6, 6-3, 10-8 victory over fellow former top-10 star Janko Tipsarevic in 4 hours, 11 minutes.
Tipsarevic had a match point, leading 5-4 in the fifth set, but the determined Raonic staved it off. Seven games later, the Canadian slugger got the key break of the match to take a 9-8 lead and served out the affair in the next game with four aces, giving him 34 bombs for the night.
Saturday's doubles rubber calls for a Serbian duo of Ilija Bozoljac and Nenad Zimonjic to take on a Canadian tandem of Pospisil and 41-year-old doubles great Daniel Nestor, himself a native of Belgrade.
Sunday's reverse singles currently pit Djokovic against the Montenegro native Raonic and Tipsarevic versus Pospisil.
Team Serbia is captained by Bogdan Obradovic, while Canada, appearing in its' first-ever Davis Cup semi, is skippered by Martin Laurendeau. This marks the first-ever meeting between the two nations.
The winner in Belgrade will meet the Argentina-Czech Republic victor in the World Group final in November.
